When dong pip install pytrnsys-process in a fresh environment and then running the processing_example.py script from somewhere else (git clone of the source repo, unrelated to my new venv into which I've "pip installed" pytrnsys-process) then I get the following error

(venv) PS C:\Users\damian.birchler\dev\pytrnsys-process-pypi-test> python C:\Users\damian.birchler\src\pytrnsys\wd1\pytrnsys_process\examples\ready_to_run\processing_example.py

This is because the script assumes that the directory layout is as it would be in a developer install. I've changed the paths of the script so that it should work independently of how/where it is run.

However, I've not checked whether this still works in a development install. Furthermore, I'm not sure if api.REPO_ROOT is still needed now? Maybe not and it can be removed? I know it's still referenced in some places, but I mean whether it's still neded theoretically or whether it could be refactored away. I don't mind it being there, just that having removed one reference now, I wanted you to double check.

Cheers

@sebastian-swob: Would you now increase the fix version for this merge request?

[sebastian-swob]

@zuckerruebe Yes I would merge main into this branch and then increase the version in the toml file

@zuckerruebe Why would you run the processing example outside of the cloned git repo?

Because I wanted to test an installation of pytrnsys-process I did with pip install pytrnsys-process. ;)
